T-Shirt Size and Measurement Guide
A size label is only a starting point. The most reliable way to choose a graphic tee is to measure a shirt you already like, compare those measurements with the chart on the product page, and think about how you plan to wear it.

What you need
- A shirt that fits the way you want the new shirt to fit
- A flexible measuring tape or straight ruler
- A flat, firm surface
- The size chart shown on the InkMerge product page
1. Smooth the comparison shirt flat
Button, zip, or straighten the shirt when applicable. Lay it on a table or floor without stretching the fabric. Smooth wrinkles gently so the garment keeps its natural shape.
2. Measure the chest width
Measure straight across the front of the shirt from approximately one inch below one armhole to the same point below the other armhole. Keep the tape level. This flat measurement is often called garment width or chest width; it is not the same as measuring all the way around the body.
3. Measure the body length
Measure from the highest point of the shoulder near the collar down to the bottom hem. Keep the shirt flat and the tape straight. Compare this with the length listed in the product-page size chart.
4. Compare the garment—not only your body
Two people with the same body measurement can prefer different fits. One may want a closer everyday fit while another wants more room, a longer silhouette, or space for layering. Compare the new garment measurements with a shirt whose fit you already understand.
5. Consider how the shirt will be worn
- Everyday fit: Compare with the shirt you reach for most often.
- Relaxed look: Compare with a roomier shirt rather than automatically sizing up.
- Layering: Allow room for the base layer you expect to wear underneath.
- Tucked styling: Pay close attention to body length.
- Group photos: Let each person choose from measurements instead of assigning sizes for them.
6. Use the chart on the exact product page
Open the product you want and select the size-and-fit help. Compare your flat measurements with the current chart displayed there. Product-page information is the final reference because available sizes and maintained measurements belong with the specific garment listing.
7. Check the selected color and size before adding to cart
After choosing a size, confirm the selected garment color, size, price, availability, and product format. Finished graphic tees are wearable shirts. InkMerge Pro DTF products are transfer-only and do not include a blank garment.
Group-order sizing
For a 12+ shirt project, use one worksheet with a separate row for every person. Record the name or identifier, selected size, garment color, quantity, and personalization notes. Ask each person to confirm the choice before the order request is submitted.
Do not estimate everyone’s sizes from memory, and do not combine several unverified lists. A single confirmed worksheet reduces corrections and follow-up questions.
Common sizing questions
Should I order my usual size?
Your usual size can be a starting point, but garment measurements are more reliable because fit preferences and shirt construction vary.
Should I measure my body or a shirt?
For this comparison method, measure a shirt that already fits the way you want. The product-page chart describes the garment, so garment-to-garment comparison is the clearest match.
What if I am between two sizes?
Compare both width and length with shirts you own, then choose based on the fit you prefer and whether you plan to layer. InkMerge cannot choose a personal fit preference for you.
Can InkMerge confirm a size for me?
InkMerge can help explain the chart, but the final choice belongs to the customer. Send questions through the contact page before ordering when a measurement is unclear.
